Struct HashSum 

pub struct HashSum { /* private fields */ }

Holds a hash sum.

Typically used for representing the hash of a chunk or the hash of file. Sum can be a maximum of 512 bits/64 bytes.

Implementations

impl HashSum

pub const MAX_LEN: usize = 64usize

Max valid length of a hash sum

pub fn to_vec(&self) -> Vec<u8>

Returns a new vec containing the hash sum.

pub fn slice(&self) -> &[u8]

Returns the hash sum as a slice.

pub fn len(&self) -> usize

Returns the length of the hash sum in bytes.

pub fn is_empty(&self) -> bool

Returns true if the hash sum is empty.

pub fn truncate(&mut self, new_len: usize)

Truncate hash length.

Trait Implementations

impl Clone for HashSum

fn clone(&self) -> HashSum

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HashSum

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for HashSum

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> From<T> for HashSum

where T: AsRef<[u8]>,

fn from(v: T) -> Self

Converts to this type from the input type.

impl Hash for HashSum

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<&[u8]> for HashSum

fn eq(&self, other: &&[u8]) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<Vec<u8>> for HashSum

fn eq(&self, other: &Vec<u8>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for HashSum

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
